Just as Dormammu was about to boast of his achievements to his sister, Su Ming, hiding under the bed, grabbed the Nightfall Greatsword with a reverse grip and thrust it through the bedboard.
There was a simultaneous sound of 'crack' and 'splat', and Dormammu, who was holding Omar's hand with a smug expression, seemed to shoot up like a rocket.
Omar reacted, grabbing Dormammu's hand at the critical moment, but this space was linked to the Dark Dimension, and in her human form, she couldn't match Dormammu's strength and was shaken off.
Witnessing this, she hesitated no longer and immediately transformed into a dark elemental form identical to Dormammu, becoming a black humanoid figure rippling with waves.
Su Ming slapped the ground and darted out from under the bed to her side, looking at Dormammu floating in the sky, clutching his bottom with a grimace.
N Metal can isolate energy, while X Metal is the manifestation of creativity from the neighboring DC Creation. These two unfamiliar metals caught Dormammu off guard, undoubtedly injuring him.
Had he been in his giant form, such a wound wouldn't have been an issue, but he was human-sized and distracted by his sister when the ambush struck, the injury almost slicing him open.
However, with the aid of the Dark Dimension, his healing was as fast as lightning, and the once gleaming silver gash now faded to a mere glow.
Su Ming flicked the greatsword and looked at Omar beside him: "You resemble your brother; we should establish a code word to avoid cutting the wrong person."
"Is this what humans call a joke?" Omar clenched her fists and flew into the air, striking Dormammu with her dark force: "Not funny at all."
Dormammu remained unfazed, merely raised a hand to effortlessly catch his sister's attack. In the dim starlit environment, he grasped Omar's fist and gazed at Deathstroke on the ground.
"Isn't this the Supreme Mage of the Main Dimension? No wonder my usually obedient and ruthless sister has changed; it's your doing..."
"And me!" Faltin, suppressing her light, blocked Dormammu's path, her stored energy now blazing like a fixed star, illuminating the surroundings brightly.
The light didn't travel far; it met the rolling black smoke nearby, and both appeared tangible, pressing and eroding each other, creating a continuous sizzling sound.
It sounded like a rainy night, the sound of small raindrops pattering on the forest, dense and incessant.
Being fully engulfed in light was a long-forgotten sensation for Dormammu. It reminded him of his days on Earth, and his dark face formed a pumpkin-like grin.
Just as he intended to speak, Omar didn't give him the chance. She reached out with another hand, applying force with both to deliver a shoulder throw, slamming Dormammu to the ground.
Su Ming, still steadfast on the ground, promptly followed with a sword strike. The black giant sword, tinged with starlight, sliced across Dormammu's calf, severing a piece of dark matter that dissipated into the air.
But it was futile; Dormammu bounced off the ground like a ball, flying in another direction. Intangible dark matter regrouped from the air, healing his wound.
"Is this your strategy? Using Faltin's flames to buy time, temporarily converting the Prison Plane into a Fire Elemental Plane, attempting to defeat me here?"
Dormammu flexed his new calf, the dark elemental body was inconsequential to him. At his level, physical means were ineffective as long as his soul and telekinesis remained.
Dormammu's reactions were within Su Ming's expectations. First, confirming he had no internal organs, both X Metal and N Metal couldn't prevent his self-healing. Then, confirming his limbs could be controlled when severed, he was a complete energy aggregate. He could swiftly determine battlefield dynamics and act, very smart.
Indeed, Deathstroke's traps are designed for the clever.
"My original purpose here was to negotiate terms with you, but since the other two are willing to discuss multiple terms, I'll certainly choose more." Su Ming adjusted his breathing, his hoarse voice transmitting through the voice changer.
Dormammu punched away the approaching Omar, gazing down at Deathstroke: "Hasn't The Ancient One told you about me? Using spatial tricks before the Sovereign of the Dark Dimension is courting death!"
He finished, his hands began sealing, unlike ordinary warlocks he only needed gestures, no incantations required, and the powerful magic immediately unleashed.
Twisting, ever-changing spatial layers unfolded, displacing everything with another space, the ground undulated like rising mountains, and countless mismatched scenes appeared in inverted or reversed forms.
With a mere thought, Dormammu transformed the surroundings into a familiar Earth for Su Ming, towering skyscrapers, bustling streets, all intertwined.
Looking up, no longer the vast cosmos, but an upside-down city in the air. Distantly, lateral buildings and streets emerged, creating spatial chaos.
Indeed, this is Mirror Image Space Magic.
In Kama Taiji, many magics are not called by full names in casual situations, like conjuring burning weapons, essential for travel and arson, with the full name "Emperor Vishanti's Order Weapons", and Mirror Image Space Magic is fully named "Dormammu's Mirror Space".
The Ancient One once used Dark Magic, always keeping her apprentices in the dark for fear that they might be tempted by power. Little did she know that human curiosity is the most dangerous thing, and her concealments were ineffective, for when someone wants to learn something bad, nothing can stop them. Fortunately, Su Ming turned it around after taking the reins.
No matter how she tried to hide it, reality wouldn't change. The Dimension Lord of the Dark Dimension, Dormammu, excelled in both the realms of Darkness and Space.
Dormammu finished casting his spell and a smug grin appeared on his face.
In the Prison Plane, Deathstroke and others planned to alter the plane's nature to deal with him, so he simply used Spatial Ability to carve out a new plane within the sub-plane.
The difference was that there was no fire here, and everything that happened in the Mirror Space was entirely at his whim!
Apart from the enemies trapped in Mirror Space themselves, everything here could be changed at will. He could make it as big as the Earth or manifest any battlefield advantageous to him.
Mirror Space is the most suitable Gladiatorial Arena; here, neither the disobedient sister nor the two little mice could escape...
However, Su Ming, trapped in the Mirror Space, remained unperturbed, almost amused.
He gestured to Omar; she had been knocked away on purpose just to create distance and gain time for spellcasting.
The well-prepared Dark Queen also immediately began casting, a plane of Mirror Space slightly weaker than Dormammu's once again enveloped everyone.
Whatever magic the brother knew, the sister knew it all.
The brother could draw Energy from the Dark Dimension, and the sister could do the same.
This battle had just begun; how could Deathstroke not understand Dormammu's abilities? He had long prepared a grand inter-dimensional feast for Dormammu.
It's a long story, but in reality, it was just a blink of an eye. Omar manifested a burning plane akin to Hell, trapping everyone inside, where Fire Element could exert its power to the fullest.
Dormammu cast a deep glance at his sister, and Omar met his gaze with equal determination. Both were floating in mid-air, their humanoid darkness continuously swirling.
"Sister, why are you helping outsiders fight against me? Haven't I treated you well?" Dormammu still maintained his composure. His pumpkin head ablaze with Black Fire, his eyes squinting: "Have you forgotten who protected you time and again on Earth? Who brought you the flesh and blood of the Eternal Race to enhance your power? Who made you become a Dark Element so you no longer had to live in fear?"
Omar, now sporting a pumpkin head herself, her body similarly burning with wave-like Black Fire: "No need to say more, it was all you, my dear brother. Rest assured, once I defeat you and become King of Dimensions, I will confine you to a far more pleasant plane where you can live happily."
"Happy? Did that human teach you this?" Dormammu glanced at Deathstroke, who was now standing with a Great Sword in both hands, watching the spectacle below: "The path of Matter is wrong; emotions are fleeting. Only Energy is eternal! I imprisoned you for your own good, lest you embark on a wrong path with no return..."
"You didn't say that before. Back then, we were exiled by the Faltin because we pursued Matter. At that time, no one stood by us, we only had each other." Black Fire spewed from Omar's eyes, and the Black Smoke forming her body stirred more violently: "But now, the Faltin has bowed and admitted their mistake to me, accepting the coexistence of Matter and Energy. My brother, you are the one who is wrong; you have fallen, abandoned your pursuit!"
"Seems you've grown up and have your own thoughts, but you're wrong!" Dormammu began casting a spell, and a new Mirror Space appeared, dispelling the previous Hell. It was a snowy wasteland: "I want to imprison you forever until I conquer the Cosmos, to show you my Energy!"
"You betrayed our shared vision; I am ashamed of you!" Omar was unyielding, forming a Dharma Seal with her hands: "You are the one who is wrong; you have become the kind of person we most hated in the past, an intransigent person who refuses to advance. Today, I will defeat you and imprison you forever to witness my power!"
Space changed again, the environment now resembling Surtur's Muspellheim, with magma flowing everywhere, smoke mixed with embers rising.
"Childish! Aren't you using the Energy from the Dark Dimension as well? Isn't your body composed of Energy and Elements? This is not Matter!" Dormammu cast another spell.
"Ignorant! I will always strive for Matter and fleshly body, and Energy is just one of the many tools, a necessary path to achieving great victory!" Omar cast another spell.
The two in mid-air came to blows over old grudges while casting spells to change space and environment, as if they had forgotten Deathstroke and the Faltin.
On the ground, Su Ming, acting as a spectator, yawned and changed position.
The love of a Demon God is truly twisted; both siblings have dominant personalities, each wanting the other to listen to them. Ultimately, it's bound to be a matter of whose fists decide the victory.
All the talk is useless now, and with Deathstroke here, it guarantees Omar will not lose.
Layer upon layer of Mirror Spaces kept replacing and superseding the previous ones, various environments rotating like a magic lantern. It's unclear how many layers of sub-planes envelop everyone from the outside, one might have to repeat the word 'sub' dozens of times.
Even Su Ming couldn't say for sure whose space they were in now; whether it was Dormammu's control or Omar's command.
This is great; the plan can enter the second stage now.
